AI Analysis

●●SolidCozyNiche Gem

Music theory in C with enharmonic correctness—tiny, zero-alloc, 100% tested.

Strengths
  • •Enharmonically correct note resolution (Bb vs A#) is a subtle, non-obvious constraint that shows domain knowledge.
  • •No internal memory allocation makes it embeddable in resource-constrained contexts; caller controls all allocations.
  • •100% test coverage + clear CMake integration + documented API suggests genuine care for usability.
Weaknesses
  • •Niche domain: music theory libraries are not a pressing pain point for most C developers.
  • •No demo or REPL; you must compile C code to see results—friction for casual exploration.
Target Audience

C developers, music software builders, embedded systems programmers
